The Campaign for Abortion Law Modernisation, known as Calm, will take place on Wednesday.
It will be held at the Manx Legion, Market Hill, Douglas, starting at 7.30pm.
Tha campaign wants to see the 1995 Termination of Pregnancy (Medical Defences) Act updated.
Organisers say a detailed programme of events will be discussed at the meeting which will bring Calm to the attention of current and prospective MHKs, and to the attention of health professionals who may not be aware of the discrepancies between the 1995 Termination of Pregnancy (Medical Procedures) Act and the 1967 Abortion Act.
All welcome.
